Brake Discs

WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Using an impact tool without a torque socket will lead to unevenly tightened wheel nuts. This causes brake disc on-vehicle lateral runout and brake roughness.

NOTE: It is generally not required to install new brake discs to address brake noise concerns.

Remove the brake disc. Refer to FRONT DISC BRAKE article for the front disc brakes or REAR DISC BRAKE article for the rear disc brakes.
Inspect the brake discs and measure the brake disc thickness in a minimum of 4 places around the circumference of the brake disc. Record the measurements.
- Install new brake discs if any thickness measurement is less than the minimum specification. Refer to FRONT DISC BRAKE article for the front disc brakes or REAR DISC BRAKE article for the rear disc brakes.
- Install new brake discs if cracked. Refer to FRONT DISC BRAKE article for the front disc brakes or REAR DISC BRAKE article for the rear disc brakes.
- Machine the brake discs if the diagnosis has revealed vibration in the steering wheel, seat or pedal while braking. Heavily scored brake discs, similar to that caused by pads worn down to the backing plate, should also be machined. In order to machine, discs must be above the minimum thickness to machine specification. Refer to Specifications and Brake Disc Machining in this article.
